VALVE.

Application filed May 9, 1925. Serial No. 29,189.

To all whom t may cof/wem:

Be it known that I, JAMES A. MARK, a citizen of the United States, residing at Madison, in the county of Greenwood and State of Kansas, have invented certain new and useful Improvements in Valves, of which the following is a specification.

My invention is an improvement in valves of that particular type which are lemployed in connection with the manifold intake pipe of internal combustion engines for the purpose of admitting an additional quantity of air to the mixture from the carbureter. j

The primary object of my linvention is to provide a valve of this general type which in the present instance is especially adapted for use in connection with a tank through which the air passes on its way to the valve and intake pipe, and which may be used independently of the tank as a simple air-intake valve.

A further object of my invention is to provi'de an improved form of valve connected to the mea-ns'for operating the damper in the supply pipe so as to be operated in conjunction therewith; the particular construction of the valve forming an effective means for admitting .the required amount of air, or an admiXture of air and gas from the tank, to effect an economy in the running of the engines as well as produce a more etiicient mixture or charge.

lith these principal objects in view my invention contemplates a form of valve comprising a tubular casing having an inletopening at its lower end and discharge apertures through one side thereof, in connection with a turning plug formed of end members closing the ends of the casing and a stem connecting said members; the plugmember at the lower end of the casing beingl cut away at'one side on a line with the inlet to cooperate therewith in opening and closing the valve; all as hereinafter particularly described and mo-re specifically set forth in the appended claims.

In the accompanying drawings Figure 1 is a side elevation illustrating the application ofA my invention in connection with a carbureter.

Fig. 2 is a front view of the valve, including the coupling by which it is attached between the carbureter and manifold.

Fig. 3 is a plan view thereof.

Fig. 4 is a vertical sectional view through the valve and coupling, and

ed through the Vopening in the Fig. 5 is a perspective view Vof the valveplug and means for operating the same.

As Figure 1 ofthe drawings is principally .for the purpose of illustrating the ap plication of my invention it will be understood that the carbureter, 10, is of a well known or conventional type, and that the tank 1l, indicated by dotted lines, is employed in some instances to charge the air with a chemical or gas before it reaches the valve` for admission to pipe.

In carrying out my invention the valve, hereinafter particularly described, is car` ried by a coupling 12 interposed between the carbureter 10 and manifold intake pipe. 13, said coupling being of an ordinary form or a thick plate elongated in shapejwith a central opening 14 therethrough and holes 15 at its ends, the latter receiving the bolts, as 16, by which said coupling is attached to the flanges 17 and 18 on the adjoining ends of the carbureter and intake pipe respectively. The central opening through the coupling corresponds in size with the contiguous openings in the carbureter and intake pipe, and in the present instance the tubular casing 19 of my improved valve extends diametrically through this opening and yalso through the upperand lower ends of the coupling with the lower portion of said casing depending below the coupling and provided with an inlet atone side in the form of a tubular branch or coupling member 20. The tubular casing is passed upwardly through the coupling and threadupper end thereof, as illustrated in Fig. 4, to securely connect the parts together, and that part of said tubular casing which is located in the opening through the coupling is provided witha plurality of discharge apertures 21 the Vmanifold intake lin the side thereof towards the manifold intake pipe so that the valve will discharge in the direction of the flow from the carbureter. The valve-plug consists of end inembers or plugs 22, and 28 connected by a stein 24, and is rotatable in the valve-casing, said end members or plugs closing the upper and lower ends of the casing, with the upper part of the member or plug23 cut away at one side on a line with the inlet-opening 2O so that in open position of the valve the air may pass into the casing between the plug-members and be discharged through the apertures 21; that portion, as 23, of

the upper part of the plug-member 23 not cut away serving to close the inlet when the rotatable plug is turned from the position shown in Fig. 4. To provide an air-inlet independent of thel inlet-opening 2O which will feed air through the valve irrespective of the position of the valve-plug with respect to said inlet-opening there is a small passage 25 extending longitudinally through the' plug-member 23 from the lower end thereof, said passage openingV into the casing' at the upper end off the reducedr portion of said plug-member. To retain the valve-plug seated within the tubular casing the lower plug-member thereof is extended below said casing and the extension provided with a transverse. aperture 26 to receive a cotterflpin; it being noted by reference to Fig. et that' the upper plug-member is provided with an integral collar 22 bearing on the upper end of the tubular casing, andl this plughmember is also provided with an upwardly-projecting squared boss Q2 to which the valve-operating arm QS is attached.

The valve hereinbefore described is operated by the rod 3l which operates theshutter SOin the pipe leading from the body of the carbureter 10, and' for this purpose the arm 28 attached to the rotatable valve-plug isprovided with an elongated slot Q8 through which the lower end of the rod 31 is extended from the operating-arm 29 attached to the shutter; whereby the valve and shutter will be operated simultaneously; that is to say when the shutter or damper 30 is opened and closed by manipulation of the rod 3l the valve willbe likewisev opened and closed, being adjusted so that thel suction through the valve will feedI the required amount of air orv chemically-charged air from the tank with relation to the flow governed4 by the damper.

As hereinbefore stated the valve is particularlyv adapted for use inconnection with a chemical tank through which the air is drawn by suction and delivered to the inlet opening 20 passing therefrom into the valve-casing from which it is discharged or sprayed through the apertures 21 into the mixture fromv the carbureter sol as to thoroughly commingle therewith, the passage 25 through the. lower plug-member 23 at the saine time feeding a small supply of cool air from the atmosphere into thevalve. In this manner the etliciency of the gas mixture orf charge to the engines is increased at a saving of fuel ora' more economical operation", and there is also a direct cooling4 effect on the engines with a decrease in the formation of carbon. It will be. understood, of course, that the tank will contain oilsv or suitable chemicalsy which will permeate the air as it is drawnby suction through said tank on its way to the valve which serves to eflectually discharge or spray the supplemental elements into the mixture. from the carbureter.

I claim 1. A valve for use in connection with a tank to supply al supplemental charge to the mixture from the carbureter comprising a coupling having anv opening registering with the manifold intake pipe, ay tubular valve-casing extending' through the coupling and' having aA plurality of apertures in one side thereof discharging into the manifold intake pipe, connections between the tank and valve, and' a turning plug consisting of' plug-members closing the ends of the tubulareasing4 and a stem connecting said plug members', one of said plug-inembers being cut away on a line with the inlet opening in' the valve-casing.

2. A valve for use in connection with a tank to supply a supplemental mixture to the mixture from the carbureter, comprising a couplingl having anl openingy registering with the manifold intake pipe, a tubu lar valve-casingv extending through the coupling and having a branch beyond the conpling and a plurality of apertures in the body portion thereof discharging into the manifold intake pipe and a turning plug within the tubular casing consisting of plugmembers closing the ends thereof and a stem connecting said plug-members, one of the plug-members being cut away at one side on a line with the aforesaid branch to provide for openingv and closing the inlet opening to the' valve and having an extra airpassage leading from the atmosphere into the valve; together with means for operating the valve simultaneously with the damper in the pipe of the carbureter.

3. A valve attachment' for the manifold intake pipe of an internal combustion engine comprising a coupling adapted to be interposed between the carbureterand manifold and having an opening therethrough on a line with said manifold, a' tubular valve casing extending through the coupling and having an inlet-opening beyond the coupling and a pluralityy of! apertures in the body thereof discharging intol the manifold intake pipe, and a turning plug within the tubular casing consisting of plug-members closing the ends thereof a-nd astem connecting said pluglmembers, one of the plugmembers being cut away at one side on a line with the inlet opening and having an extra air-passage leading from the atmosphere intoE t'hevalve; together with an operating-"arm attached to one end of the turning-plug.
